4 cylinder 4 speed auto 373 gears. At 60 in hi gear with torque converter locked I am at 2000 RPM. Is this normal?

That sounds a bit slow. With my 3.5L auto 3.73 it would run at 80 mph at 2500 rpm. Same with my current 3.5L 5M 3.42 it runs at 80 mph at 2500 rpm

I have 3.73’s and I turn about 1800 rpm at 60. Are you sure your speedo is correct ? Do you have stock tires ?

sorry for the late reply, yep 1,800/60 and 2,000/65 ... can you verify/compare speed thru the OBD2 port vs gauge ?

That's a good point ^^^

Use your phone and a navigation app and verify your speed via GPS as well
